Why is the engine smoking? ? ? ? Don't worry, please let me go over your forklift with you. Reason 1-1: Black smoke from the exhaust pipe (due to poor combustion) ——————Partially closed choke valve Troubleshooting method: Adjustment Reason 1-2: Black smoke from the exhaust pipe (due to poor combustion) ——————Air filter blocked Troubleshooting method: Cleaning and dredging Reason 2-1: White smoke from exhaust pipe (due to engine overcooling) ——————Not enough engine warm-up Troubleshooting method: Increase the load if the engine warm-up is not enough, and then gradually increase the load after the engine is warmed up to a water temperature above 50 degrees Reason 2-2: White smoke from the exhaust pipe (due to the engine being too cold) ——————Gasoline contains water Troubleshooting method: Remove moisture Reason 2-3: White smoke from the exhaust pipe (due to the engine being too cold) ——————Water in cylinder Troubleshooting method: Troubleshooting Reason 2-4: White smoke from the exhaust pipe (due to the engine being too cold) ——————Poor atomization of fuel injection of the fuel injector, oil dripping phenomenon, and low fuel injection pressure Troubleshooting method: Check the oil nozzle assembly Reason 2-5: White smoke from the exhaust pipe (due to the engine being too cold) ——————The fuel injection time is too late Troubleshooting method: Readjust the oil supply time Reason 2-6: White smoke from the exhaust pipe (due to the engine being too cold) ——————The pressure in the cylinder is not enough, the fuel is not burned well and is excluded Troubleshooting method: Check cylinder pressure Reason 3-1: Blue smoke from exhaust pipe (due to burning of organic oil) ——————Too much oil Troubleshooting method: Release excess oil Reason 3-2: Blue smoke from exhaust pipe (due to burning of organic oil) ——————The piston ring wears too much, or is stuck by carbon deposits, causing oil to overflow Troubleshooting method: Replace or clean piston rings Reason 3-3: Blue smoke from exhaust pipe (due to burning of organic oil) ——————The gap between the piston and the cylinder is too large Troubleshooting method: Overhaul or replacement Reason 3-4: Blue smoke from the exhaust pipe (due to burning of organic oil) ——————Long-term low load (less than 40% of the rated power) far transfer Troubleshooting method: Appropriately increase the load Reason 3-5: Blue smoke from the exhaust pipe (due to burning of organic oil) ——————Air filter clogged Troubleshooting method: Disassemble and clean the air filter Reason 3-6: Blue smoke from the exhaust pipe (due to burning of organic oil) ——————The gap between the valve push rod and the valve guide is too large Troubleshooting method: Replace
